FAUCET.

SPECIFICATION forming part of Letters Patent No. 636,777, dated November 14, 1899'.

Application filed August 4:, 1 8 9 8.

To all whom it may concern.-

Beit known thatI, AU GUST EN GEL, acitizen of the United States, and a resident of Milwauke'e, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Faucets; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention has for its object to provide simple, economical, and positive self-closing faucets. v

Therefore it consists in certain peculiarities of construction and combination of parts hereinafter ,set forth with reference to the accompanying drawings and subsequently claimed.

Figure 1 of the drawingsrepresentsa partlysectional elevation of a basin-faucet embodying my improvements, the plane-of the section being indicated by line 1 1 in the succeeding figure; and Fig. 2, a plan view in section on the plane indicated'by line 2 2 in the preceding figure.

Referring by letter to the drawings, A represents the spout-section, B the base or pipeconnection section, and C the cap of the shell portion, of a basin-faucet embodying my improvements, these parts being in screw-thread union with each other. In like union with the shank D of pipe-connection shell-section B is a T-apertured casting E, having its upper end recessed to form a cup, having no opening other than that at its upper end, in which a valveless plunger F has snug engagement, this plunger being in detachable connection with the lower end of a stem G, having the usual plug-valve H thereon.

The aforesaid cup is imperforate and has the inner surface of its wall uninterrupted, the plunger engaged therewith being an inflexible, preferably cylindrical, and practically solid block; but fluid under pressure finds its way into said cup between the latter and said plunger. The plunger being an inflexible device and not subject to wear, its durability and utility are in no way impaired by the conditions under which it operates.

The casting E is virtually an extension of the shank D within the shell-section B of the faucet, the apertured portion of said casting serving to establish communication between Serial No. 687,703. (No model.)

the bore of said shank and interior of said shell-section.

The plug-valve being of expansible material, the plunger may be adjustable on stem G to regulate expansion of said valve, and, as is usual in the art, said stem has water-tight play in a gland I within the spout-section of the faucet-shell. A spiral spring J is shown seated on the gland around the valve-stem under tension against a flange of a combined nut and push-pin fitting K, run on the screwthreaded upper end of said stem. By adj ustment of this fitting K the tension of spring J may be varied and compensation had for wear of the valve.

The push-pin portion of fitting K has loose engagement with an aperture in cap C, and opposing this push-pin is a cam-disk L, arranged in a circular housing M, cast in one piece with said cap, open at one side. A fulcrum-lug b of the cam-disk engages a notch in the circumference of housing M, and said disk is provided with a segmental aperture 0, engaged by a boss 01 central of said housing.

In loose fit on the housing M is a shell N at the lower end of a lever P, and provision is had for limiting play of the lever. The shell constitutes a closure for the open side of said housing and has a pin 6, that engages an aperture f in the fulcrumed cam-disk. The aforesaid shell end of the lever is shown maintained in its engagement with the housing M by means of a screw g, engaging one end of the housing-boss d, and another screw h, shown engaged with the other end of said boss against said housing, has no function other than to improve the finish of the faucet.

Expansive force of spring J and fluid-pres sure in the aforesaid cup against plunger F hold the valve to its seat, and inasmuch as the slotted cam-disk is loosely engaged by pin 6 of the shell end of lever P the latter will stand normally as shown in Fig. 1. When the lever is actuated to cause pressure of the fulcrumed cam-disk against the push-pin portion of fitting K, the valve H will move down away from its seat, and the plunger F, moving with said valve, displaces fluid accumulated in the cup portion of casting E, above specified. On release of the lever the spring J reacts to seat the aforesaid valve, and the rise of plunger F in the fiuid-cup will cause a suction in said cup that tends to prevent concussion of said valve against its seat. Fluid under pressure finding its way into the aforesaid cup operates against the plunger to insure positive seating of said valve, it being apparent that the seating operation is with the pressure. The spring merely quickens the seating of the valve, as it is a fact that withoutsaid spring fluid under pressure gradually accumulating in the aforesaid cup will operate against plunger Fto in time reseat said valve. The plunger being cylindrical and made to fit against a portion of a valve of well-known spherical type,there is no fluid pressure intermediate of the two acting to retard upward movement of the same; but in the present case a retardmcnt of upward movement of said valve and plunger is had entirely by suction in the plunger-cup.

lVhile I have shown and described my improvements applied to a basin-faucet, they are just as applicable to bibs and a variety of other faucets, the cup for engagement of the plunger being variously devised to suit any species of faucet. It also follows that lever mechanism other than that herein set forth may be utilized to operate the valvestem, provided with a plunger reciprocative in a fluid-cup, and the preferred lever mechanism may be utilized to operate on valvestems of faucets devoid of said plunger and cup.

Having now fully described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. A faucet having its cap provided with a circular open-side housing extension, a camdisk fulcrumed in the housing, a lever having a shell end in loose fit on said housing to constitute a closure for the open side of same, a pin connecting the shell end of the lever with cam-disk, and means for maintaining engagement of said shell end of the lever with the aforesaid housing, said cam-disk being operative in conjunction with said lever to unseat the faucet-valve.

2. A faucet having its cap provided with a circular open-side housing extension, a camdisk fulcrumed in the housing, a lever having ashell end in loose fit on said housing to constitute a closure for the open side of same, a pin connecting the shell end of the lever with the cam-disk, means for maintaining engagement of said shell end of the lever with the aforesaid housing, and a combined tension-nut and push-pin adjustable on the valve stem of the faucet in opposition to said camdisk.

3. A faucet having the shell portion thereof provided with a fluid-cup, a cup-engaging plunger on the valve-stem of the faucet, a circular open-side housing extended from the cap of the faucet-shell, a cam-disk fulcru med in the housing, a lever having a shell end in loose fit on said housing to constitute a closure for the open side of same, a pin connecting the shell end of the lever with the camdisk, and means for maintaining engagement of said shell end of the lever with the aforesaid housing, said cam-disk being operative in conjunction with said lever to unseat the valve.

4. A basin-faucet having a T-apertured cup-casting in union with the pipe-connection section of its shell, a plunger on the lower end of the spring-controlled valve-stem engaging the cup portion of said casting, a combined tension-nutand push-pin fitting adjustably on the upper end of said valve-stem, a circular open-side housing extended from the cap of the faucet-shell, acam-disk fulcru med in the housing to bear upon said push-pin, a lever having a shell end in loose fit on said housing to constitute a closure for the open side of same, a pin connecting the shell end of the lever with the cam-disk, and means for maintaining engagement of said shell end of the lever with the aforesaid housing.

5. A basin-faucet having the pipe-connection shank of its shell provided with an apertured extension the free end of which has the form of a closed-bottom cup, and a plunger on the valve-stem of the faucet in snug sliding engagement with said cup.

6. A basin-faucet having the pipe-connection shank of its shell provided with an apertured extension the free end of which has the form of a closed-bottom cup, a spring-controlled valve-stem, and a pl unger on the valvestem in snug sliding engagement with said cup.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of Wisconsin, in the presence of two Witnesses.
